Icon not showing in Creative Cloud when developing Adobe Premiere Pro Plugin using UXP

Hello everyone,

I hope this is the right place to ask this technical question.

I'm developing a adobe premiere pro plugin with UXP. I understand it's in beta but hope I get some light on my issue.

I can't get my panel icons to display. The panel shows a default/blank icon instead of my custom icons.

What I've tried:
1. Following Adobe's icon documentation with proper naming convention (icons/plugin-icon.png in manifest,
icons/plugin-icon@1x.png and icons/plugin-icon@2x.png as files)
2. Using both 23x23 (panel icons) and 48x48 (plugin icons) sizes
3. Testing with different paths and filenames
4. Verifying icons are correctly copied to dist folder when building my plugin

Environment:

My manifest.json structure:

{
  "version": "0.7.17",
  "main": "index.html",
  "manifestVersion": 5,
  "host": [
    {
      "app": "premierepro",
      "minVersion": "25.3.0"
    }
  ],
  "entrypoints": [
    {
      "type": "panel",
      "id": "apps",
      "icons": [
        {
          "width": 23,
          "height": 23,
          "path": "icons/iconLight.png",
          "scale": [1, 2],
          "theme": ["all"]
        }
      ]
    }
  ],
  "icons": [
    {
      "width": 48,
      "height": 48,
      "path": "icons/plugin-icon.png",
      "scale": [1, 2],
      "theme": ["darkest", "dark", "medium", "lightest", "light", "all"],
      "species": ["pluginList"]
    }
  ]
}

Is this a known limitation of UXP Developer Tool, or am I missing something? Do icons only
display when published to marketplace?
